My Ryzen 9 7950X3D died a couple months ago. I just tried rebooting one day, screen went black during startup, and that was the end of it. Nothing but two red POST lights on the motherboard after that.
I had been donating some CPU time to a couple BOINC projects (solving math, physics, and biology problems), so it's possible that might have contributed to its demise. Although, I typically had it throttled to not exceed about 25% of CPU usage, so I would think the CPU should have been able to handle it. But, ¯_(ツ)_/¯.
I've only seen one other CPU die in my entire life, and that was years ago when I was playing around with overclocking an old CPU. So, I was rather surprised when my 6-month old CPU went to an early grave.
The fine folks at AMD were kind enough to RMA the.dead CPU and replace it with a 9950X3D, which runs like a champ. But it also rarely gets above 5% CPU usage, which seems like a bit of a waste. But, I'm not in a hurry to use any of that excess capacity to run another BIONC project any time soon.
